Two word puzzles a day, in your language

Made from the words you are learning, with a few minutes of cards.

Two minutes of it, right here

Words that stay learned

Each one comes back the day before you'd lose it.

Your morning puzzle

A word, a grid and a chess problem, in the language you're keeping.

The difference

Miss a Tuesday.
Nothing breaks.

Ninety days · a week away

Those seven blank squares are a holiday. Anywhere else they end a streak worth a year of work and hand you a backlog on the Monday you come back. Here they cost seven squares and nothing else.

Miss a day.Nothing breaks, and nothing is lost.
A time budget, not a queue.Two, five or fifteen minutes. You pick. Five days away still produces a five-minute session.
Nothing counts what is waiting.No screen anywhere shows how many cards are due, so there is no number to clear and no debt to feel.

Ten languages

Three of them the big apps never built.

ἙλληνικήKoine Greek
לְשׁוֹן הַמִּקְרָאBiblical Hebrew
LutherdeutschLuther’s German

Alongside French, Spanish, German, Turkish, Czech, Tagalog, Hindi and Modern Hebrew. If you are reading the text rather than ordering a coffee, there was never an app for you, and now there is one that treats it as a daily habit rather than a degree.

Why it works

Built on three findings, not on a mascot.

61%Recalling beats re-readingA week after studying, people who practised recalling remembered 61% of a passage. People who simply read it again remembered 40%.Roediger & Karpicke, Psychological Science, 2006
317Spacing is not optionalAcross 317 experiments, spaced study beat cramming, and the right gap grows with how long you need to hold on to it. That gap is what decides when a word comes back here.Cepeda, Pashler, Vul, Wixted & Rohrer, Psychological Bulletin, 2006
−0.36Rewards undo wantingAcross 128 experiments, rewarding somebody for completing a thing reduced their desire to do it again. A streak is exactly that kind of reward, which is why there isn’t one.Deci, Koestner & Ryan, Psychological Bulletin, 1999

Who makes it

One engineer, a summer, and the research.

Made by Seb Moon, who has a master’s degree in engineering and two and a half years in product design engineering. Quotidia was built over the summer, alongside a solo master’s project that was awarded a Distinction.

Backed by scienceSpaced repetition, one of the best-replicated findings in memory research.
Optimised for memoryEach word comes back on the morning you are about to lose it.
Accelerated by agentsAI tools let one person build, test and run all of it.

Selected for the LUinc pre-accelerator at Loughborough University. Fewer than 5% of applicants were chosen for this cohort.
